Can saunas prevent viral replication?


Saunas may contribute to preventing viral replication, according to insights shared in discussions on heat and immune system interactions. Dr. James DiNicolantonio discussed the role of heat shock proteins, specifically heat shock protein 70, in binding to viral components and potentially preventing their export from cells. This interaction was demonstrated in animal models where exposing animals to heat shock resulted in a reduction in viral replication. In humans, a small clinical study indicated that regular sauna sessions reduced the occurrence of the common cold by 50%.

These effects are thought to be related to the immune response similar to fever, where increased body temperatures can inhibit the replication of viruses. However, while there is some epidemiological and experimental data suggesting benefits, the direct application to humans, especially concerning specific diseases like COVID-19, remains less certain and more research is needed to confirm these effects 1 2.
